Object casting shadow at scale 0,0,0

Hi
Having an issue with animated objects, scaled down to zero, that keeps casting shadows.
Very annoying issue that happened to me in the past, but this time i can't go around it..

    Any idea why its happening with soft shadows?

     

    Thanks Cerbera

    Yep that's it. Area shadows are much more accurate than soft shadows, and it could be that Soft Shadows (which are only a render-cheap approximation) doesn't know what do with shrinking object scale.

    That's why i used them for this project- to show the client a fast preview with shadows.

    Spent more time resolving it than rendering the preview ..:)

    That's OK - we can still do it with soft shadows if we have to, but we just have to cheat ;)

    The SS is actually accurate until frame 4, when the object is at the smallest it gets before it disappears.

    So why not just keyframe the shadows off or down to 0% density on frame 5 ?
